Be it known that I, EDWARD O. 'lmsmwr, e citizen of the United' States,reeidiugg m -Brooklyn, in the county of Kings tote o of New York, haveinvented cert-em new and useful Improvements in Joint Stifienem forFolding Conteihem'of which the following'is a specification.

My present improvement relates to a new form of joint stifienin meansfor preventing the collapse of 01 ing, scored, oints in foldable pasteboard display containers where scoring is used for predeterminingthefolding points in permitting said container or its component parts to befolded flet.

While my invention is hereih shown in connection with displayoontainers, it is noted thatthe invention as claimed is not limited inits use m couteineie ,nor to (115- Another object of my invention is tomake such stiffening means integral with the box thereby obviating thenecessity of providing 21. separate moons therefor, and at the some 25time to provide that such a, ilevicehe ve quickly set into and out. ofoperative posltion. 7

la the drawing spective view 0 herewith, Fig. 'l. is a perecontainershowing the improvement thereon.

Fig. 2 is a. sectional view, slightly enlarged, taken on the line Ab,Fig. 1, looking in the direction of the arrow.

Fig. 3 is a. rear View of said container showing the easel or supportportion partly folded. y Fig. l is a. sectional view taken on the line4-4, Fig. 2, looking in the direction of the arrow. 7

Fig. 5 is a. sectional view taken on the line 5--5, Fig. 4, looking inthe direction of the arrow.

. While in Fig. 1, I have shown my etifieningdevice located upon aneasel or tilting bottom of a cello, sing or folclehle containergenerally demo by 2, it is obvious that other euch joimtures es meyhefound to reis of the coed eeeel or tilting ty ole portion 1, which isintegrally attached. to the displa. hohteiner, wherciii the container isprovi ed with a. lololihg or collapsing easel portion-1, usually cl witha. portion of the hoxstructure, more -emlly foldable against the boxstmcture in order to make it as neerly rectangular es phle,

so as to economize in shipping space, as is well known in the customarypractice.

However, in conteihers of the type herein disclosed the weight of the m.carried or shipped therein is such tot the portion 1, wheuo encd' out,and the conteiner, placed in fispley position, for exposing the floods,may collapse under the weight of a. ll container thereby defeating thepurpose for which the eceel portion 1 was designed.

Usually the collapse of the easel in Mente'iiier of this cleee is alsoclue to the foot that the scoring, indicated by the dotted lines 3throughout the drawings herein, may

be rather deeply dome, and thus-weaken the easel or supporting sections.In other instances, cornstent folding and opeiii of the easel portion 1may further wealzen t e scoringeo that its inherent stifiness' isdestroyed and the easel portion will then tend to remain in its foldingposition rather than in the extended and supporting position as shown inFig. l.

I have "found in practice that while the K easel portion 1 may be foldedin a number of places that there is generally one or more positions outof the plurality of scoring points that may he provided with astifi'ening means without the necessity of having every scored pointprovided. In the present instance, I have found that the folding points4, Fig. 3, formed et one of the scoring oints ,3 when roperly providedwith sti' cuing means, will permit the wool to he set up to support anyreasonable couditiczc of load, and incidentally permit of a. very largenumher'ozl conse uerit collapsing and extending actions wit outundesirolole collopse occurring when the box is set up for. zlieploy.

My improved stifiemihg moons coins in to the line of the provision,treusvorsely scoring, of e bendable hinged, tab or lug '8, Ereterehly ofeemi-ciiwuler form, which is looked out of the well of the side uponwhich the ecoring occurs. lo the petitistance the tel) member iepreterehlye with ltS largest diet/er 1 EN? m lllll to its associatedside at a point'i, Fig. 5, so that in efiect, when thistab is bent at aright angle to its inoperative position, it acts to bridge the scoredline and thereby stidens the scored member.

Naturally, in the process of manufacture, the cutting of the stifienerinto the side wall and transversely to the scored line 3, as abovenoted, also permits the stidener element to become itself scored so asto permit ready folding at the scored joint when the stidener is innon-operative position, as is disclosed at a, Fig. 3,wherein the easelportion is shown partly collapsed against the bottom of the box 2 Whenthe easel portion as shown in Fig. 3, is fully extended as in Fig l, thestidener member lies in the plane of the wall and partakes of theextending action of its associated wallsection, and after the easelportion 1 is extended into support position, then the stifiener element6 is pushed inwardly by the finger thereby causing it to take theposition as shown 1n Fig. 5, and, owin to the substantially right angle,sheltike projection of the tab 6, across the line of scoring 3, the saidscoring is prevented from being bent inwardly or outwardly, due to thetransverse truss action caused by the re-argement of the tab 6 at rightangles to the sides of the said easel ortion 1 and transverse to thelineof scormg 3.

It is obvious that various geometric forms of tabs may be out in the boxwithout despirit of the disclosure made herein, and it is also obviousthat, while l have shown the stifi'ener-tab as being integral with theside of the box and blanked therefrom, that other modifications may thusbe made for the same purpose, all of which l would consider as beingequivaparting from the lent of the structure herein disclosed.

What ll claim is: i. lna device ot the character described,

, a member provided with a, line of told, and

a partially cut-out stiii ening means disposed transverse to said line,said difiening means being bendable upon a score line transverse tosaidline of told,

2. lin combination, a supporting device;

and asu oitin member rovided with a Lessors scored line out fold,providing relatively foldahle sections; said member being pro= videdwith a stifiening means partially out out of both said foldahlesections, said means being scored at, its base portion and beingdisposable substantially erpendicularto said line to stiffen saidmeinhe3. A toldab-le display container having a scoredfoldable easel thereon,and a partially cut-out bendable stihening means located transverselyto, the line of scoring, the said bendable means having its bending basedeveloped transversely to the line of said scoring.

4. A foldable display container of the class described, having a scoredtoldable portion and a bendable cut-out tab located" transversely to theline of the scoring upon said foldabl'e portion, said'tab being adaptedto be bent at rightangles to the plane of said foldable portion wherebyto bridge and prevent inversion of the score on said portion. Y 1

5. in combination, a supported device, and a supporting member providedwith a scored line of told providing relatively toldable sections, and asingle tab member being cut out of said ioldable sections on both sidesof the fold line thereof, the'said tab being provided with a score lineat its base and transverse to the said told lines, and being bendable atright angles to the said told line whereby to hold said foldablesections against inversion.

6. A toldin' support for boxes oi? the class describes. comprising asection of said box being'bendable to cause said support to lie flat tothe box when in closed position and provided with a partially cut outtab portion for a single score at itsb portion, the said score beingformed at right angles to the line of scoring between sections at saidfolding mrtion whereby when said tab v is bent upon said score line, itforms an unscored bridge portion located in such posi tion as to preventinversion of said i ldable portion when the tab is bent .at rightanglesto the plane of said folding rtion.
